Not the big hard wired ones! I only anticipate using one for, at most, charging two laptops at the same time. Looks like the LT bricks max at about 180 watts each. The TV is an LED and has very little draw and the Blue ray player is pretty low (need to check both again, but I recall both together being below 100W)

I am very pleased with my Morningstar 300 watt sine wave inverter. It will do what you want and actually has up to a 600 watt rating for a few minutes.

What I like most is the low idle draw of 0.4 amps when running but not providing any load (or very small load such as charging things) and the Search feature, which can be set on it. In search, with no load the inverter shuts down entirely, and only puts a pulse out about once a second to see if anything has been turned on. With that feature, you never have to think about turning it off when not in use as the search function reduces the load to about 15 to 20 mA. It works like a charm, and I have not shut the inverter off since I put it in. When plugged in at home the PD 4645 converter/charger keeps the tiny load of the inverter from running the batteries down, and on the road the solar and TV charge keep it going.

I only charge one laptop, mine is an Apple Mac Book Pro. BTW, I am at a Forest
service campground as I write this, the Morningstar is providing power for the message.
